Abstract

We computed the equation of state at T = 0 for BCC and HCP He-3 with diffusion Monte Carlo. The most recent SAPT(2) interatomic interaction, and an ab-initio three-body force were used. The ground state was projected starting from a Nosanow-Jastrow wave function to stabilize the crystalline phase. The comparison with different extrapolations of the experimental EOS at T = 0 will be discussed. The BCC-HCP phase transition is consistent with experimental results. (C) 2000 Elsevier Science B.V.
